title: [Case of Wegener's granulomatosis associated with mediastinal lymphadenopathy].
abstract: A 54-year-old asymptomatic man was admitted to our hospital because his abnormal chest radiograph finding became worse. A chest radiograph and a chest computed tomography showed a mass in the right upper lobe and mediastinal lymphadenopathy. Thoracoscopic partial lung resection was performed. The specimens showed vasculitis and geographic basophilic necrosis palisading histiocytes and neutrophils. Wegener's granulomatosis was diagnosed. After resection, mediastinal lympahdenopathy was gradually improved in spite of no drug therapy. We report a rare case of Wegener's granulomatosis associated with lymphadenopathy.
